This paper presents some practical implications of a theoretical web desktop analysis and addresses microposts in the Social Web contextual sense and their role contributing diverse information to the Web as part of informal and semi-formal communication and social activities on Social Networking Sites (SNS). We reflect upon and present the most pervasive and relevant sociocommunication functio...

Since the United States’ National Academy of Engineering’s Grand Challenges were first publicly articulated in 2008, engineering educators have used its ideas to motivate their work. While there is a sense of moral imperative around pursuing selected Challenges, work that critically examines the ethics of the Grand Challenges has so far been rare. In this paper, examining the process surroundin...

It is known that the sequence 1, 2, 1, 1, 2, 2, 2, 1, 1, 2, 1, 1, 2, 1, 1, 2, 2, . . . of lengths of blocks of identical symbols in the Thue–Morse sequence has several extremal properties among all non-periodic sequences of the symbols 1 and 2. Its generating function W(x) is equal to ∏∞ k=1(1 + x(2 +(−1))/3). In terms of combinatorics on words, for any given x ∈ (0, 1) and > 0, we prove that e...

This paper discusses the integration of cultural and natural heritage aspects of landscapes. It presents arguments for the further integration of interests but also points to the potential for conflicts between cultural and natural heritage interests. These are predominantly at the site-management level. The important role of the historical layer is stressed as an integral part of the environme...

We present an algorithm for computing the greatest integer that is not a solution of the modular Diophantine inequality ax mod b 6 x, with complexity similar to the complexity of the Euclid algorithm for computing the greatest common divisor of two integers.

An important function of language is to create and develop interpersonal relationships in communication. In inquiry we share and coordinate our beliefs about how the world is. But we also take a stance and socially orient ourselves toward possible acts, attitudes, and states of affairs. We evaluate possibilities as desirable, appropriate, horrible, trivial, permissible, wonderful. We make deman...

In [9], the author introduced quasirandom permutations, permutations of Zn which map intervals to sets with low discrepancy. Here we show that several natural number-theoretic permutations are quasirandom, some very strongly so. Quasirandomness is established via discrete Fourier analysis and the ErdősTurán inequality, as well as by other means. We apply our results on Sós permutations to make ...

Let f (m, n) denote the number of relatively prime subsets of {m+ 1, m + 2,. .. , n}, and let Φ(m, n) denote the number of subsets A of {m + 1, m + 2,. .. , n} such that gcd(A) is relatively prime to n. Let f k (m, n) and Φ k (m, n) be the analogous counting functions restricted to sets of cardinality k. Simple explicit formulas and asymptotic estimates are obtained for these four functions. A ...

A raison d’être of social science is the claim that its knowledge can produce solutions to social problems such as poverty, underdevelopment, and ecological degradation. However, I take the view that the current constitution of the social sciences cannot solve problems because it is an integral part of what causes problems. In short, social scientific theory regarding social problems is deeply ...
